Size doesn’t always matter. Despite its compact dimensions, NANOZWERG is a full-featured monophonic analogue synthesizer. With VCO, an additional sub-oscillator and its 12dB-slope-multimodefilter, NANOZWERG offers multiple bass- and lead-sounds. In addition, NANOZWERG offers a noise-generator and also works as an effects-processor using its external audio-input.
Here is an overview to NANOZWERG’s configuration:

The analogue VCO generates four waveform shapes: Triangle, saw tooth, rectangle and needle-impulse. The base pitch can be switched over a four-octave-range, while fine-tune can be specified within a range of one octave. The sub-oscillator with two mixable octave settings completes the NANOZWERG’s sound foundation. The noise generator can alternatively replace the sub-oscillator to create non-harmonic sounds. Finally, a glide-control can be used to tie notes with portamento.

The state-variable multimode-filter runs with 12dB slope per octave and offers Lo-, Hi- and Bandpass-modes as well as notch-filtering and resonance up to self-oscillation. Cutoff can be modulated manually, by LFO and by the ADSR-envelope simultaneously. In addition, pitch-dependent cutoff-frequency can be achieved using the key follow function. Finally, LFO modulation can be replaced by the VCO output signal.

The LFO offers four waveform shapes including sample & hold as well as a one-shot-function, where the selected waveform is played only once after a gate-trigger, thus imitating a simple envelope. Besides the cutoff-frequency, the LFO can also modulate the pitch or the VCO rectangle’s pulse width.

The ADSR-envelope allows modulation of the filter’s cutoff-frequency and the VCA-output, with positive or negative excursion. Selectively, the VCA can also be opened by a gate-trigger to free the envelope for exclusive filter use.

For integration into a modular system or use with an analogue sequencer, NANOZWERG offers several control inputs. There is CV/Gate for pitch control and note length as well as CV-inputs for cutoff-control, the VCA and LFO speed. The LFO also offers CV-output.

The audio-input allows signals to be fed into the VCF and VCA. NANOZWERG can be controlled by MIDI from any compatible keyboard or DAW. Note commands are received as well as pitch-wheel (+/- 2 semitones) and modulation-wheel data, the latter controlling the filter’s cutoff frequency.

MFB’s NANOZWERG has the following dimensions: 140 x 130 x 35 mm.External power supply included."

Yamaha SK10 SN 3765 with Original Case

"Yamaha's SK-series are combo-keyboards with synthesizer, organ, brass and string sections. The SK-10 was the first of the SK-series, released in 1979 - the SK-20, 30 and 50D followed in 1980, and the SK-15 in 1981, possibly as a replacement for the SK-10. The SK-10 is the only one in the series that does not incorporate a synth section, but has organ, brass and string sections that can all be played together for more interesting combinations..."

"The SH-101 is very cool, especially for techno, drum&bass and ACID! It's a monophonic bass synthesizer. Its sound lies somewhere between the TB-303 and a Juno 106 bass sound. It has a lot of simple but cool features. You can control the VCF, pitch, LFO or all from the pitch bender. It has a white noise generator, arpeggiator with up, down and up/down patterns and a simple real-time sequencer. The LFO offers random, sine, square or noise waveforms. And normal or auto portamento effects give you that elastic bass sound. There are external clock inputs for the sequencer and arpeggiator, CV/GATE inputs and outputs and a CV hold pedal.

Unfortunately there is no patch memory storage and although it has no MIDI there are upgrades available for it from many analog service companies that will allow you to incorporate it into any MIDI studio environment. It can also be controlled by MIDI using a CV/MIDI converter. It's great for bass sounds or bubbly analog effects."

"rare multi synth fully analog with very nice string sections attack release eq hi and low strings
but even better the synth section it sounds very like a polyphonic korg MS-10
low pass / band pass filter (very nice) cut-off resonance e.g. up down very squelchy ms sounding
4 additive waveforms for oscillator and white noise raw like ms again
full envelope for synth section
and the best thing its fully polyphonic
on the back is has stereo or separate output for string or synth
also a cv gate input for synth section and a vcf controller input
typical korg joystick controller pithcbend with lfo section
filter and pitch can be modulated by lot or noise generator for extra mad sounds
the allover sound is very old korg retro 70s and in your face

this delta has just been fully serviced by analog circus all knobs are working perfect "
